摘要
We address beam space reduction method inside which proper analog beamformers are selected for hybrid beamforming millimeter Wave (mmWave) system. We apply insights from spatial multiplexing theory on beam subspace selection and show that computational effort of searching for desired beamformers can be significantly reduced. A simplified channel throughput estimation measure is also devised to further lessen the complexity in the course of beamformer searching. Simulation results demonstrate that near-optimal performance can be achieved with significantly reduced complexity.
